A girl sent by a guy to get close to another guy. Her role is to get info on him through (conversation, text messages, etc.) Then she gives that information back to the guy, Then that guy uses the information to set the other guy up. The bitch is basically a informant (🐀). NEVER TRUST A BITCH. 💯

When your girl is giving you head, you pull out, cum on her face, and brush your junk over her forehead like a paintbrush, watching her expression go completely blank like the painting
My girl told me to surprise her that night, so as I was about to finish, I gave her a Mona Lisa.... Surprise!!!!!

A person (usually girl) who are shy and have a small subtle smile.
But the smile is the sweetest thing ever and lights up the room

That look on a girls face when you cum on her tits. Not a full on grin, but just a subtle smile that you aren't sure what it means, but you think she's enjoying it.
Sherry gave me her Mona Lisa Smile when I came all over her tits, but it went away after my buddy Tim nutted all over her face.
